Few studies have specifically focused on the uncertainty of demand forecasting despite the fact that uncertainty is the one of greatest risks for governments and private partners in PPP projects. This study presents a methodology for finding robust contract conditions considering uncertainty in travel demand forecasting in a PPP project. Through a case study of an urban railway PPP project in Korea, this study uncovered the risk of excessive government payments to private partners due to the uncertainty in contracted forecast ridership levels. The results allow the suggestion that robust contract conditions could reduce the expected total level of government payments and lower user fees while maintaining profitability of the project. This study offers a framework that assists contract negotiators and gives them more information regarding financial risks and vulnerabilities and helps them to quantify the likelihood of these vulnerabilities coming into play during PPP projects.

This Study reviews theoretical argument about the effect of retirement earnings test on the labor supply of the aged which is controversial issue in OECD countries and analyze the effect on the incidence of re-employment, re-employment period of suspended officials and the possibility of re-retirement through Government Employment Pension Corporation data. It consists of 178,363 public officials who received pension benefit or disability pension in January 2005. The main result of this research shows that public officials re-employed were 8,086 which is 4.5% of total retired, and median survival time of suspended pension payments is 3.3 years. Also the median re-employment period of 100% suspended officials is about 20 month shorter than that of 1/2 suspended officials and it is shown in regression analysis that the possibility of re-retirement by 100% suspended officials is statistically significant higher than those of 50%. It specially expects greater influence if includes in case taking lump-sum or no making effect of re-employment because current system withhold pension payments even by earned income itself. Therefore, this analysis suggests suspension of pension payment properly applied according to the age and income together with "Delayed Retirement Credit" or "Partial Pension" for developmental alternatives of civil servant's suspension of pension payments. Furthermore, It is urgently needed that distinctive quality data about re-employment including earnings to perform deep-empirical research for effective policy. Lastly, it is extremely necessary to reinforce management system of Government Employment Pension Corporation.

In the Health Insurance System of South Korea, patients must pay high out-of-pocket expenditures for the medical service by uninsured medical benefits. So, the government implemented a policy to relieve the burdens of patients by lowering the uninsured selective-medical treatment costs in August, 2014. This study investigate the policy effects of selective-medical treatment(SMT) on the medical service's usage and cost with severe lung cancer patients. The patients are selected in one university hospital(with 1,000 beds), between one year before and after policy implementation. The study find that the usages of outpatient(visit number) and inpatient (length of stay) are not changed by statistically significant. It means that there are no effect in medical service behavior between before and after the policy. In medical expenses, outpatients decreased in their out-of-pocket payments by policy, but total medical expenses and insured medical benefits is not changed, because of the increased another medical insurance fees. For inpatient, although the SMT costs are statistically significant decrease, the total out-of-pocket payments and insured medical expenses are not changed statistically significant. Those findings show that the political decision making about SMT made lowing the selective-medical expenses, but total insured cost and patient's out-of pocket money were not changed by the new increased medical insurance fees. It means that the policy about SMT gave no particular benefit for patients. So, it need another benefit plans to lower the medical expenses of severe lung cancer patients with a high medical service usage and much total medical expense.

This study aims to analyze in depth the operation of the Public Lending Right(PLR) system that is implemented in 34 countries in the world in order to propose the ideal operation of PLR system. The PLR system is that authors receive payment because they lose the sales opportunities due to the loan of their books by libraries. Among 34 countries implementing the PLR system, 31 are European countries and 20 countries enforce the copyright law for the operation of the PLR system. Fund for the PLR is financed by the budget of the central government in 25 countries and payments are made on the basis of loans data in 20 countries. Writers, illustrators, translators are eligible to receive payments in many countries. 17 countries provide payments to the authors who have contributed to books lent out by libraries.

Social Impact Bonds(SIBs) has emerged as a promising way to finance proven social services programs, fund what works, and drive government accountability and has increased fast. In this context, this study examines and classifies the structure of SIB focusing key criteria of the main steps through two-step cluster analysis. Analysis results are as follows. First, the main commissioners of SIB are the ministries of the central government. And in terms of the stage of invest, there are usually two or three investors mainly consisting of social finance organizations. Second, in terms of target and age of SIB beneficiaries, it focuses on the adolescent and youth. Third, in the outcome evaluation stage, the results show that in most cases outcome payments are determined by a validation of service provider or government administrative data. However, the rate of payments are based on the comparison of the program beneficiaries to other comparable groups is 23.8%. Finally, The results of two-step cluster analysis are as; 'mix of central government and social finance organization', 'multiple agent including private organization', and 'multiple social provider'. Among three types, 'multiple agent including private organization' shows the most active participation between agents and the most systematic outcome measurement and management. The results of this study imply that the importance of the method to manage and measure outcome in SIB structure. Moreover, the consist of commissioners or investors is needed to expanded more.

In the absence of a male provider the state must decide how far and under what conditions it will provide for the mother and her children. In the case of lone mothers, there are three main possible sources of income: the labour market, the absent father, and the state. However, the relative proportions of these three sources vary significantly from country to country as well as from individual to individual within the group of lone parents. Until very recently the UK has been alone among countries of the EU in allowing lone parents to draw benefits without making themselves available for work so long as they have dependent children. However, in the 1990s, the UK government introduced major changes to his policies regarding lone parents. The UK government attempted to restrict the role of the state as a source of income for lone parent families. At the beginning of the 1990s, the emphasis in the UK was put on securing more money from 'absent fathers' to maintain. However, the policy was unsuccessful and by the mid-1990s attention to the only other possible source of income for lone parent families, the labour market, was stepped up, notwithstanding the ambivalence of politicians about the desirability of women with young children entering employment. From 1998 the Labour government introduced a series of reforms aimed at reducing both worklessness and poverty by raising welfare payments to families both in and out of work, improving financial incentives to work and introducing a more proactive welfare system. The results presented here suggest that these policies have raised the employment rates of lone parents by around 5 percentage points, or 80,000. These employment gains have come from a welfare reform package that does not require lone parents to search for jobs, or uses time limits in welfare programmes. In addition these gains have been achieved despite generous increases in welfare payments for lone parents who do not work. These earnings gains combined with the more generous welfare are making rapid progress in reducing lone parents' poverty.

It was the era, from 1876 to 1910, that some dramatic changes, including an influx of foreign dyes and the beginning of the modern dyeing manufacture, happened in Korea. This paper explores what dyes were sold in the market in this period, who was the main seller of the goods, and how the dyers produced their products. A wide range of natural dye stuffs coexisted with the various kinds of aniline dyes, alizarin dye and synthetic indigo in the market. Coloring materials had been sold by hwapi-jeon, a group of official merchants who acquired a privilege of monopoly from the government. However, the dyes were also traded by sang-jeon and yakguk merchants in the nineteenth century. Most of the synthetic dyes sold in Korea were produced in Germany or in Japan later, and imported in large amount by Chinese, Japanese and German merchants. Yet there also existed Korean merchants and peddlers who sold the goods to the local consumers. Dyers were male and female who belonged to the middle class. They received the orders and payments from the government or merchants. Not only did they dye textiles, threads, cotton, paper and leather, but they also redyed clothes. Indigo dyers were differentiated from other dyers. Modern dyeing manufacture, which was presumably forced to keep pace with the productivity of the weaving process, appeared in the 1900s. It was a branch of the modern weaving manufacture.

The main purpose of this study is to examine the rewards for "Family Care" from the Japanese Long-Term care policy, to investigate the effects of "The commodification of Family Care" after the introduction of "The Long-Term Care Insurance", and to find out the institutionalization of reward system for "Family Care". First of all, the socialization of "The Long-Term Care" is redefined to be the commodification of family care in this study. Based on this definition, the commodification of family care and the government's involvement are analyzed in conjunction with considering the role of family in the process of Long-Term Care supply, the social evaluation for family care, the family carers' home environment and the position in the labor market. In result, the commodification structure of family care in the Japanese Long-Term Care policy is found, and it helps to understand the reason why the cash payments was just partially introduced.
